I turned it off and then back on. It is working as designed now.
Why can't you just turn off the reminder if you don't want it? I can't look right now, but isn't that an option? Or you could use the regular alarm feature.
What's annoying is Siri doesn't recognize this as an alarm, so if you ask to see your alarms, or your bedtime alarms, it doesn't know what your're talking about.
